ASoC: Intel: bytcr_rt565: fix missing assignment to ret_val 

Currently, the check that ret_val is not -ENOENT is always true and
the quirk bit BYT_RY5651_MCLK_EN is never being cleared because ret_val
is always zero at this point from a previous assignment earlier on.
I believe that ret_val should actually be assigned to the return from
devm_clk_get() as this can return -ENOENT (from a deeper call to
clk_get_sys) and that was the original intention to check this.

Detected by CoverityScan, CID#1460228 ("Logically dead code")
